Hieromonk

A hieromonk is a monk who is also ordained to the priesthood, and so may celebrate the sacraments for his monastery or parish, as distinct from a monk who is not ordained.

Monk and priest together

The hieromonk unites two states that are in principle separate: he has professed the monastic life and he has also been ordained a priest, so that he may celebrate the liturgy, hear confessions and administer the sacraments, which an unordained monk cannot, while continuing to live under monastic vows. The office exists because a monastic community needs priests among its members to celebrate the sacraments, and because the priesthood is thereby joined to the monastic life in a single person.

The pool of the episcopate

Because the bishops of the Eastern churches are drawn from the celibate clergy, and in practice from the monastic clergy, the hieromonks are the body from which bishops are chosen, so the office is a station on the path to higher office as well as a role in its own right, and a hieromonk of standing may be raised to archimandrite and thence to the episcopate. Entry is by the ordination of a monk to the priesthood. The hieromonk thus represents the monk-priest of the Eastern churches, the member of a monastic community who has also received the priesthood, and the office marks the point at which the monastic and the sacerdotal are joined, supplying the monasteries with their priests and the church with its future bishops.

Mount Athos in northern Greece, a self-governing monastic republic under Greek sovereignty and the special protection of the Ecumenical Patriarchate, is home to twenty ruling monasteries and a population of monks unusually dense with hieromonks relative to ordinary monasteries elsewhere, since pilgrims visiting Athos rely on resident hieromonks specifically for confession, communion and other sacraments not available from an unordained monk, making the priesthood-within-monasticism a practical necessity of daily life on the mountain rather than an occasional convenience.

Athos maintains a long-standing prohibition, the avaton, on the entry of women onto the peninsula at all, a restriction defended by the monastic communities there as integral to their contemplative way of life and repeatedly challenged by outside critics, including at the level of European Union institutions, as a form of gender discrimination inconsistent with general principles of equal treatment; the dispute remains unresolved, with Greek and Church authorities maintaining the exemption and no legal mechanism currently in force that has actually ended the practice, leaving Athos as one of the clearest documented cases of a still-functioning closed religious space defined explicitly by the exclusion of one sex.
